My backwoods packin? gun is a stainless Super Blackhawk, Bisley 3 3/4 inch in 44 mag. Carried in a Simply Rugged pancake holster. Usually Crossdraw. sometimes I carry my vintage Colt 1911 in 45ACP or my Redhawk 44 mag.
If I was buying a lightweight everything gun I would probably go with a 6 inch Light frame S&W 44 mag as several of the others have noted or possibly a GP 100 in 44 Special or perhaps in 357 mag if its not a high risk bear area. A light frame 45LC would also be a good choice. Funny thing is I don?t own such a gun as I usually carry a full size steel gun.
